Heinkel He219: An Illustrated History of the Third Reich’s Dedicated Home-Defence Nightfighter
by R. Frances Ferguson.
This new book is the product of a lifetime interest in the subject - and extensive research spanning more than a decade. Writing started in 2012, shortly after the publication of the ‘He 219 Research Paper’ when a number of readers suggested that he should have written the definitive history of the type.
At that time, however, Ron felt that he did not have sufficient depth of knowledge.
The Research Paper was a “… first step in setting right the historical record” - a first step only.
However, publication of the Research Paper brought forth new photos, documents and information. This ultimately developed into this new work, which gives the reader a comprehensive and highly detailed study of the Heinkel He 219.
This is an academic limited edition from the specialist publisher Air Research inended for the serious Luftwaffe enthusiast and historians and will only be produced in limited numbers.
It is distributed exclusively by Wing Leader.
